Ex Wal-Mart CEO's deferred pay: $140 million

Duke, who retired Jan. 31, had $140.1 million in deferred compensation at year's end, Wal-Mart said Wednesday in its annual proxy filing. That's more than $27 million over what Duke had accumulated in retirement accounts in 2013, when governance experts noted that was more than 6,000 times greater than what the average Wal-Mart employee had stashed in 401K retirement accounts.

Duke's successor, C. Douglas McMillon, saw his compensation soar to $25.6 million from $9.5 million. The bulk of McMillon's gain came from a $23 million stock grant. Wal-Mart said the grant is tied to McMillon's promotion and payouts tied to three years of corporate performance metrics.
